From the Camelot Herald:
Talk to Lady Mirabelle in Castle Sauvage, Druim Ligen, or Svasud Faste to begin the egg hunt; the first event of the Rites of Spring. Quests range from level 15 - 49 on classic and normal servers, and 35 - 49 on PvP and PvE servers. Join the hunt, and the fight!

Story:Spring has come, (Your Race). Everything is coming back to life after the long winter, and all the crazies are coming out of the woodwork. I mean, all the animals are getting ready for new life. Yeah, new life!

It's during this time of year that mysterious eggs appear. Strange and delic... I mean magical. Certainly not delicious. Not at all.

The beasts and birds are tricksy, though, and tend to hide the eggs in places where we cannot go, or at least could not survive for very long. In the fields of strife where children play is their favorite place - the lands you call battlegrounds.

You seem to be a clever and daring (Your Race); also good-looking. Perhaps, in your adventures in these lands of battle, you might gather some eggs and bring them to me? As it is a dangerous area, you will be rewarded with a small number of realm points.

Summary:Search Thidranki for hidden Spring Eggs. When you have five, return them to Lady Mirabelle at your main borderkeep.
